abaqus-scripting

Define time-varying amplitudes. Use when user mentions ramp, time-varying, cyclic, pulse, or gradually increasing loads. Does NOT handle static constant loads.

Analyze multi-body contact. Use when user mentions parts touching, friction between surfaces, bolt-plate contact, press fit, or assembly with contact.

Complete workflow for coupled thermomechanical analysis. Use when user mentions thermal stress, thermal expansion, or temperature causing deformation.

Download and manage abqpy API documentation. Use when user asks about API documentation, API reference, or downloading Abaqus docs.

Complete workflow for dynamic analysis. Use when user mentions impact, crash, drop test, transient, or time-varying response. Handles explicit and implicit dynamics.

Workflow for fatigue and durability analysis - cycle counting, damage accumulation, and fatigue life prediction.

Define initial conditions and predefined fields. Use when user mentions initial temperature, pre-stress, residual stress, or import from previous analysis.

Define contact and interactions - contact pairs, tie constraints, connectors. Use when user mentions contact, friction, tie, parts touching, or bonded surfaces.

Complete workflow for modal/frequency analysis - extract natural frequencies and mode shapes. Use for vibration analysis and resonance avoidance.

Optimize fillet/notch geometry. Use when user mentions stress concentration, fillet optimization, reshaping surfaces, or reducing peak stress. Moves surfaces only.

Complete workflow for heat transfer analysis - steady-state and transient thermal. Use when user asks about temperature distribution, conduction, convection, or heat flow.

Read analysis results. Use when user asks about maximum stress, extracting displacements, reaction forces, or exporting results. Post-processes ODB files.

Execute topology optimization via Tosca CLI. Use when user mentions running optimization, tosca optimize, check run, SLURM job, post-processing optimization results, smoothing, STL export, or validation run.

Master skill for Abaqus FEA scripting. Use for any finite element analysis, topology optimization, or Abaqus Python scripting task. Routes to appropriate specialized skills.

Complete workflow for topology optimization. Two paths available — (a) CAE API path using TopologyTask + ObjectiveFunction + OptimizationProcess for Abaqus built-in optimization, or (b) Tosca CLI hybrid path where CAE builds the FE model, writeInput() generates the .inp, a .par file defines the optimization, and `tosca optimize` runs it. Tosca requires full Abaqus license with Tosca module (not Learning Edition).

Tosca .par file authoring for topology, shape, bead, and sizing optimization. Covers block syntax, design responses, constraints, objectives, optimization parameters, and STL export. This is the definitive reference for hand-written .par files.

Define boundary conditions - fixed supports, displacements, symmetry. Use when user mentions fixed, pinned, clamped, supported, or constrained. Does NOT handle loads or forces.

Export Abaqus geometry and results. Use when user mentions exporting to STL, STEP, CSV, or generating input files for external use.

Create and manipulate Abaqus geometry - parts, sketches, extrusions, CAD import. Use for any geometry creation task including box, cylinder, or STEP/IGES import.

Create and manage Abaqus jobs. Use when user asks to run the analysis, submit the job, execute the model, or generate input file.

Apply forces and pressures to structures. Use when user asks to apply a force, add pressure, put a load on, or mentions gravity, point loads, or distributed forces.

Define material properties for FEA models. Use when user mentions steel, aluminum, Young's modulus, elastic, plastic, density, or asks about material properties.

Generate finite element meshes. Use when user mentions mesh, elements, nodes, refine mesh, mesh size, or asks about element types like C3D8R, C3D10, S4R.

Configure output requests - field outputs, history outputs. Use when user asks what results to save, output variables, reduce output file size, or history output.

Complete workflow for static structural analysis. Use when analyzing stress, displacement, or reaction forces under constant loads. For strength and stiffness evaluation.

Define analysis steps and procedures. Use when user mentions static analysis, dynamic step, frequency analysis, heat transfer step, or asks about analysis type, time increments, or nlgeom.
